Creating Advanced Entrypoints for Containers

There has been much confusion around the container entrypoint and parameters. This post will shed some light on this topic and present an script to serve as an flexible entrypoint.

  • Container image builds using img
  • Lightweight Kubernetes using k3s

Talk about observability at Devsmeetup

Last week I had the chance to talk about observability at our local Devsmeetup. As usual, after the talk we had a very lively discussion about monitoring in general but also about Prometheus and long term storage.

Talk about news from the container space at ContainerConf #ConConf2019

Last week I had the honour of talking again at ContainerConf 2019 in Mannheim. I consider this conference to be the best German event in the container space. Just like in the two previous years I talked about news with regard to containers. But this year, I decided to stop focussing on Docker but covered Kubernetes as well.

How to use the Pod Concept for an Isolated Environment in #Docker Workshops

When working with Kubernetes for the first time, the concept of a pod feels strange because Docker has not prepared us for it ;-) But the idea of a pod can be useful when working with Docker. This post will demonstrate how to use a pod to deploy isolated environments for workshops.

Using #ShellInABox for #Docker Workshops

In a workshop situation, attendees must be able to follow the material in a personal hands-on environment. Docker helps isolating such environments and prevents issues from using the attendees’ laptop. Let me show you how to provide dedicated environments using shellinabox.

Workshop about #Docker for Advanced Users at DevOps Essentials #DevOpsentials19

This week, I attended a new kind of conferencecalled DevOps Essentials organized by dpunkt, heise Developer and iX. They decided to have most half-day workshops with only one keynote-like talk per day. I was able to contribute one of the half-day workshops for advanced users of Docker.

Container Native Build Using Insulatr

Products for continuous integration and continuous delivery have become a commodity. But among them is a growing number isolating build steps in containers. Instead of using a fully integrated product, I have created a tool called insulatr to execute builds in containers without the need for a server component or scheduler.
